Dynamic Equilbrium

Question 1

The rates of the _____ and backward reactions are _______

Answer 1

• forward

* equal

Question 2

The concentration of ______ and _______ are ______

Answer 2

• forward
• backward
• constant

Question 3

What happens if the conditions change?

what is le chatliers principle

Answer 3

is the conditions change the system will change equilibrium position to counteract the change imposed on it.

Question 4

What happens if you increase the concentration?

Answer 4

Increasing the concentration of the reactants will move the equilibrium position to the right hand side of the reaction.

• forward reaction happens more

Question 5

What happens if you decrease the concentration?

Answer 5

Decreasing the concentration of reactants will move the equilibrium position to left hand side of the reaction.

• Backward reaction happens more

Question 6

What happens if you increase the temperature?

Answer 6

If you increase the temp the system is going to try to decrease it. The equilibrium position shifts int the endothermic direction.

• shifts to the left (reactant side)

Question 7

What happens if you decrease the temperature?

Answer 7

The equilibrium position shifts in the exothermic direction.

• shifts to the right (product side)

Question 8

What happens if you increase the pressure?

Answer 8

If we increase the pressure the system will try to decrease the pressure.

• Higher pressure favours the side with fewer moles of gas

Question 9

What happens if you decrease the pressure?

Answer 9

Lower pressure factors the side with more moles of gas.
